Heat Treating Aluminum Bronze C95400

Heat Treating Aluminum Bronze C95400

Heat Treating Aluminum Bronze C95400

(OP)
Does anyone have any experience with heat treating Aluminum Bronze C95400? Heat treatable grades of Aluminium Bronze contain 9.5 to 11.5 % Al, with iron , small amounts of nickel and manganese. The reason for heat treating is increasing tensile strength and hardness with improved impact strength. Quenching from 1600F and tempering from 800-1200F will obtain this increase strength.

Does anyone know what the process is? Is it like a Quench and temper steel , where the maxium hardness is obtained "as quenched" then tempering with lowering hardness from higher tempering temperatures? Or is it a Solution treatment? From the 1600 F quench and Age treatment from the 800-1200F? Where time at temperature is critical?

Any help would be appreciated

See ASTM B505.

The following is an excerpt from the article "Heat Treating of Copper Alloys" from ASM HANDBOOK Volume 4 Heat Treating:

Complex α-β aluminum bronzes are those aluminum bronzes whose normal microstructures contain more than one phase to the extent that beneficial quench and temper treatments are possible.  These copper-aluminum alloys, with and without iron, are heat treated by procedures somewhat similar to those used for the heat treatment of steel and have isothermal transformation diagrams that resemble those of carbon steels.  For these alloys, the quench-hardening treatment is essentially a high-temperature soak intended to dissolve all of the α phase into the β phase.  Quenching results in a hard room-temperature β martensite structure, and subsequent tempering reprecipitates fine α needles in the structure, forming a tempered B martensite.
